Abstract

The device has a chassis (1) providing a lifting mechanism (17) equipped with a downshift cable and crank. The crank permits to lift a load through a vertical carriage having four directional wheels offering a rotation of more than 90 degrees. An articulated lever (18) connected to a sprocket controls rotation of the wheels. The lever allows transversal and longitudinal displacement of the load without rotating the load.

Description

La présente invention concerne un dispositif pouvant déplacer uneThe present invention relates to a device capable of moving a

charge longitudinalement et transversalement sans la faire pivoter.  load longitudinally and transversely without rotating it.

Le déplacement de charge longue avec changement de direction s'opère généralement en la faisant pivoter, ce qui nécessite un espace important.  The long load movement with change of direction is generally done by rotating it, which requires a large space.

La manutention et le déplacement de cette même charge dans un espace réduit sont alors rendus très compliqués ainsi que le chargement dans un véhicule.  Handling and moving this same load in a reduced space is then made very complicated, as is loading into a vehicle.

Le dispositif selon l'invention permet de remédier à cet inconvénient. 10 Il comporte en effet selon une première caractéristique, un mécanisme de levage à câble démultiplié, équipé d'une manivelle qui permet de lever une charge importante par l'intermédiaire d'un chariot vertical.  The device according to the invention overcomes this drawback. According to a first characteristic, it in fact comprises a lifting mechanism with a multiplied cable, equipped with a crank which makes it possible to lift a large load by means of a vertical carriage.

La deuxième caractéristique est un autre mécanisme permettant la rotation de quatre roues à plus de 90 centralisées sur un levier articulé. Ce 15 même levier permet de démultiplier l'effort exercé par l'utilisateur. Il est pourvu d'une articulation, ainsi quand il est relevé à l'horizontale, l'effort exercé sur la droite ou sur la gauche provoque une rotation simultanée des quatre roues. L'utilisateur exerce une poussée latérale ou transversale sur le dispositif suivant la direction souhaitée pour déplacer la charge.  The second characteristic is another mechanism allowing the rotation of four wheels with more than 90 centralized on an articulated lever. This same lever makes it possible to multiply the effort exerted by the user. It has an articulation, so when it is raised horizontally, the force exerted on the right or on the left causes a simultaneous rotation of the four wheels. The user exerts a lateral or transverse thrust on the device in the desired direction to move the load.

La difficulté à surmonter a été de rendre possible une rotation des roues avec une amplitude aussi importante sans l'utilisation de moteur ou de boîtier mécanique, mais avec un mécanisme le plus simple possible, offrant une meilleure fiabilité et un coût moins élevé. Cela a été réalisable en fixant un pignon sur chaque axe de roue et une chaîne les reliant entre eux par 25 deux rendant ainsi possible une rotation supérieure à 90 . Sur chacun des deux ensembles pignon et chaîne est fixée une biellette à un angle très précis qui est à son tour boulonné à une bielle réglable permettant d'affiner le réglage de la synchronisation des quatre roues. Une tringle fixée sur un axe de roue avec un levier articulé vissé à l'autre extrémité commande la 30 rotation des roues.  The difficulty to overcome was to make it possible to rotate the wheels with such a large amplitude without the use of a motor or mechanical box, but with the simplest mechanism possible, offering better reliability and lower cost. This has been possible by fixing a pinion on each wheel axle and a chain connecting them to each other in pairs, thus making rotation greater than 90 possible. On each of the two pinion and chain assemblies is fixed a link at a very precise angle which is in turn bolted to an adjustable link making it possible to refine the adjustment of the synchronization of the four wheels. A rod fixed to a wheel axle with an articulated lever screwed at the other end controls the rotation of the wheels.

Selon des modes particuliers de réalisation: - les deux pales de levage peuvent être mobiles en translation pour permettre un ajustement en fonction de la charge à déplacer.  According to particular embodiments: - the two lifting blades can be movable in translation to allow adjustment according to the load to be moved.

- le mât du dispositif peut-être plus long permettant ainsi d'accéder à des 35 hauteurs plus importantes.  - The mast of the device may be longer, thus allowing access to greater heights.

- la transmission de la rotation des roues par la chaîne et la bielle peut-être remplacée par des axes équipés de pignons coniques pour permettre une rotation plus précise.  - the transmission of the rotation of the wheels by the chain and the connecting rod can be replaced by axes fitted with bevel gears to allow more precise rotation.

Le dessin annexé illustre l'invention: - la figure représente l'ensemble du dispositif de l'invention.  The accompanying drawing illustrates the invention: - the figure represents the entire device of the invention.

En référence à ce dessin, le dispositif comporte un châssis (1) et un châssis (2).  With reference to this drawing, the device comprises a chassis (1) and a chassis (2).

Le châssis (1) est composé d'une embase en forme de U avec deux profils triangulaires (3) pour rigidifier l'ensemble.  The chassis (1) is composed of a U-shaped base with two triangular profiles (3) to stiffen the assembly.

Quatre ébauches usinées (4) sont soudées à chaque extrémité. Elles sont équipées de deux roulements chacune facilitant ainsi la rotation des quatre roues. Sur ces pièces sont montées un axe en forme de L (5), sur 10 l'axe une roue (6) pneumatique ou pleine suivant la nature des sols, un pignon (7) et un plat (8) solidarisé avec la pièce (5). Une chaîne (9) lie les pignons (7) par deux et une bielle (10) vissée sur les pièces (8) transmet le mouvement à l'ensemble. Deux profils en U sont soudés verticalement et parallèlement, l'ouverture face à face sur la traverse (11) pour former le mât 15 (12). A leurs sommets un autre profil en U (13) avec deux renforts (14) rigidifie l'ensemble. Deux poulies (15) qui peuvent être montées sur roulement à bille sont fixées en haut du mât pour le passage du câble (16).  Four machined blanks (4) are welded at each end. They are equipped with two bearings each, thus facilitating the rotation of the four wheels. On these parts are mounted an L-shaped axis (5), on the axis 10 a pneumatic or solid wheel (6) depending on the nature of the soil, a pinion (7) and a plate (8) secured to the part ( 5). A chain (9) links the pinions (7) in pairs and a connecting rod (10) screwed onto the parts (8) transmits the movement to the assembly. Two U-shaped profiles are welded vertically and in parallel, the face-to-face opening on the cross-member (11) to form the mast 15 (12). At their summits another U-shaped profile (13) with two reinforcements (14) stiffens the assembly. Two pulleys (15) which can be mounted on ball bearings are fixed at the top of the mast for the passage of the cable (16).

Le mécanisme de levage (17) est fixé du même côté que le levier de commande de changement de direction (18) afin d'éviter le déplacement de 20 l'utilisateur pour les deux manipulations. Ce même levier articulé (18) , est fixé sur le mât (12) et sur un axe de roue (5), il permet la rotation de celles-ci. Le châssis (2) est composé d'un cadre aux dimensions légèrement inférieures à la cote intérieure du mât. Quatre galets (20) sont vissés à chaque extrémité du châssis (2) pour assurer le guidage à l'intérieur du mât. Deux pâles (21) sont fixées déportées vers le bas du châssis (2) pour permettre d'atteindre le sol en position basse. Le câble (16) est fixé sur le châssis (2) et sur le mécanisme de levage (17) en passant par les deux poulies (15), il permet la monté et la descente du châssis (2).  The lifting mechanism (17) is fixed on the same side as the direction change control lever (18) in order to avoid the movement of the user for the two manipulations. This same articulated lever (18) is fixed on the mast (12) and on a wheel axle (5), it allows the rotation thereof. The chassis (2) is composed of a frame with dimensions slightly smaller than the interior dimension of the mast. Four rollers (20) are screwed at each end of the chassis (2) to provide guidance inside the mast. Two blades (21) are attached offset to the bottom of the frame (2) to allow reaching the ground in the low position. The cable (16) is fixed to the chassis (2) and to the lifting mechanism (17) passing through the two pulleys (15), it allows the chassis to be raised and lowered (2).

- selon une variante non illustrée, la transmission de la rotation des roues 30 par la chaîne et la bielle peut-être remplacée par des axes équipés avec pignons coniques pour permettre une rotation plus précise.  - According to a variant not shown, the transmission of the rotation of the wheels 30 by the chain and the connecting rod can be replaced by pins fitted with bevel gears to allow more precise rotation.

A titre d'exemple non limitatif, le châssis aura des dimensions de l'ordre de 130 cm pour la longueur, 80 cm pour la largeur et 180 cm pour la hauteur afin de pouvoir être chargé dans un petit camion.  By way of nonlimiting example, the chassis will have dimensions of the order of 130 cm in length, 80 cm in width and 180 cm in height so that it can be loaded into a small truck.

Le dispositif selon l'invention est particulièrement destiné à la manutention.  The device according to the invention is particularly intended for handling.
